The
Control Panel
lets you make various
settings for the US-144’s functionality.
On Windows XP and Windows Vista, the
US-122L & US-144 Control Panel
shortcut
can be found in the Windows Start menu in
the Windows control panel and also under
All Programs\TASCAM\US-122L &
US-144
.
On Mac OS X, the
US-122L & US-144
Control Panel
is located in the
Applications folder. Other useful audio and
MIDI settings for Mac OS X can be found
in
Applications/Utilities/Audio MIDI
Setup
.
The
Control Panel
is divided into the fol-
lowing two sections.

Audio Performance
The US-144 driver temporarily stores input
and output audio samples in buffers. The
size of these buffers can be adjusted.
A smaller buffer size will reduce the delay
when monitoring the audio signal, but will
require your computer to perform the pro-
cessing faster. If the processing does not
occur in time (e.g., if other system opera-
tions are occurring), you may hear clicks,
pops, or dropouts in the audio signal.
A larger buffer size provides more safety
against such problems caused by other sys-
tem activities, but will produce greater
delay when monitoring the audio signal.
You select the buffer size that works best
for your system.
On the Windows version of the US-144
Control Panel, the Audio Performance set-
ting permits you adjust the buffer size that
will be used by all audio applications. The
Lowest Latency setting is the minimum
buffer size, and the Highest Latency set-
ting is the maximum buffer size.
On Mac OS X, the buffer size is deter-
mined by each audio application.
Consequently, there is no Audio
Performance setting on the Mac OS X ver-
sion of the US-144 Control Panel. Some
applications select the buffer size automati-
cally while others permit the user to select
the buffer size. Please consult your audio
application’s documentation for details.
